Function:
(output speed vs. feedback).
Function:
error set in H-21 Motor Feedback Speed Error
to be exceeded before enabling the function
selected in H-20 Motor Feedback Loss
Function.
Function:
This function is used to monitor that the
application follows the expected speed profile.
In Closed loop the speed reference to the PID
is compared to the encoder feedback (filtered)
In open loop the speed reference to the PID is
compensated for slip and compared to the
frequency that is sent to the motor
(DR-13 Frequency).
The reaction will be activated if the measured
difference is more than specified in
H-25 Tracking Error for the time specified in
H-26 Tracking Error Timeout.
A tracking error in closed loop does not imply
that there is a problem with the feedback
signal! A tracking error can be the result of
torque limit at too big loads.
H-24 Tracking Error Function

Warning/Alarm 78 Tracking Error is related to the Tracking
Error Function.
H-25 Tracking Error
Range:
Function:
10 RPM
[1 - 600
Enter the maximum permissible speed
*
RPM]
error between the motor speed and the
output of the ramp when not ramping. In
open loop the motor speed is estimated
and in closed loop it is the feedback from
encoder/resolver.
H-26 Tracking Error Timeout
Range:
Function:
1 s
[0 - 60 s] Enter the time-out period during which an error
*
greater than the value set in H-25 Tracking Error
is permissible.
H-27 Tracking Error Ramping
Range:
100 RPM
[1 - 600

RPM]
H-28 Tracking Error Ramping Timeout
Range:
Function:
1 s
[0 - 60 s] Enter the time-out period during which an error
*
greater than the value set in H-27 Tracking Error
Ramping while Ramping is permissible.
H-29 Tracking Error After Ramping Timeout
Range:
Function:
5 s
[0 - 60 s] Enter the time-out period after ramping where
*
H-27 Tracking Error Ramping and H-28 Tracking
Error Ramping Timeout are still active.
3.7.3 H-4# Advanced Settings
Parameters to configure advanced controls for Open/
Closed Loop, control principles: V/Hz, Adv. Vector,
Sensorless Vector, and Closed Loop Vector, Constant or
Variable Torque, and Overload Mode.
DET-618C
Function:
Enter the maximum permissible speed
error between the motor speed and the
output of the ramp when ramping. In
open loop the motor speed is estimated
and in closed loop it is the feedback
from encoder/resolver.
